环十二醇固定床液—固相连续法脱氢制环十二酮工艺

Technology of Producing Cyclododecanon from Cyclododecanol by continuous Dehydrogenation in Liquid - Solid - Phase in fixed - bed

在小试的基础上进行了单管模拟固定床放大试验,考察了反应温度、进料流量对脱氢反应的影响,确立了中试工艺的优化条件:反应温度为245～255℃,WHSV=0.4。

On the basis of small - scale test, the amplifying test of single tube to simulate fixed - bed was made. The effects of the reaction temperature and the feed rate for dehydrogenation were studied, and the optimal operational method of pilot - plant test was obtained. The reaction temperature is 245 - 255℃, and the WHSV is about 0.4.
